{"id":"CVE-2026-33571","kind":"vulnerability","aliases":["CVE-2026-33571"],"related":[],"title":"Intel VTune Profiler: out-of-bounds read lets local users crash the system","description":"Out-of-bounds read for the Intel(R) VTune(TM) Profiler software before version 2026.0.0 within Ring 1: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"Intel VTune Profiler before 2026.0.0 has an out-of-bounds read in its Ring 1 device driver component.
